TRAClNG-CLOTH IVIANGLE Specification of Letters Patent.

Patented June 26, 1906.

, T @ZZ whom, t may concern:

Be it known that I, WILLIAM B. WAECHTER, a resident of Garfield, Bergencounty, in the State of New Jersey, have invented certain new and usefulImprovements in Tracing- Cloth Mangles, of which the following is aspecification.

This invention relates to a machine technically known as a mangler, andis in the present instance used for a special purpose in the manufactureof tracing-cloth or the like 1n which sizing or starch is employed, itbeing necessary in order to produce perfect tracingcloth, that thesizing or starch be thoroughly pressed or forced into the interstices ofthe fabric, so that the same will become properly impregnated thereinand not be liable to erasure, which occurs in ordinarily preparedtracing-cloth. By means of my improved machine the sizing is sothoroughly forced into the fabric that cracking is less liable, as thesizing and the fabric become practically one, which is not the case whenthe sizing is confined to the surface of the fabric, as in bending thesurface of the fabric has a tendency to work away from the sizing.

To attain the objects before mentioned, I employ the special means whichwill hereinafter be described and claimed in conjunction with theaccompanying drawings, forming part of this specification, wherein-Figure 1 illustrates my improved machine as viewed from the front, thestarch or sizing reservoir being shown in section. Fig. 2 is a sectionalend elevation of my improved machine, the section being taken on a linea, c in Fig. 1; and Fig. Sis an enlarged cross-sectional view of themangling-roll, showing the engraved or roughened periphery.

Like numerals and letters of reference indicate corresponding parts inthe several views.

Referring to the drawings, the numerals 1 and 2 indicate theframe-standards, which are suitably anchored to the floor or the like.As will be seen by Fig. 2, the standard 2 is provided with a guideway 8,'the standard 1 being likewise provided with a guideway.

Within said guideways boxes 4 4 are slidably fitted, Fig. 1, and withinthe boxes 4 4 a wooden pressure-roll 5 is rotatably mounted by means ofthe trunnions 6 6 thereupon. Below the roll 5 I place a coactingpressure or material roll 7, which is rotatably mounted in the boxes 8 8by means of the trunnions 9 9 thereon, the said boxes 8 8 being slidablymounted in the ways 3 in the standards 1 and 2. In order that the roll 7can be leveled and v maintained so I provide threaded adjustingjacks 10,one under each box 8. (See Fig. 2.) The jacks 10 engage at their lowerextremities a nut 11, while the upper end 12 of the said jack isprovided with a Spanner-nut 13. The end 12 can enter an opening 13 intheboxes 8 as a security against displacement, the nut 10 resting upon theshelf 14 at the bottom of the ways 3. By means' of these jacks the rolls5 and 7 can be leveled simultaneously and their peripheries alwaysmaintained in contact. When the roll 7 is leveled it becomes a fixture,and the contacting pressure of these two rolls is supplied by the upperroll 5, the said pressure being produced by weights 15 15, which areadjustably mountedupon the ends of levers 16 16, which, as will be seenin Fig. 2, are fulcrumed to the standards 1 and 2, as at 17; but theweights 15 may be otherwise applied, if desired. The

levers 16 have attached thereto connectingrods 18 18, which are composedof two members 19 19', connected by turnbuckles 20 20 for the purpose ofadjustment. The upper ends '19 of the rods 18 18 are connected tosecondary levers 2l 21, which are fulcrumed to the standards 1 and 2, asat 23, the said standards being slotted, as at 24 24 to receive thelends of the said levers, and, as at 25 25, for the said levers to passthrough, the slots 25 25 being long enough to allow said levers 21 afree up-and-down movement. Through an openin 26 in the levers 21 athreaded spindle 27 free y passes, the lower end of which engages theboxes 4 4, as shown and is free to rotate therein. The spindles 27 carryshoulders 28, upon which the levers 21 rest, the threaded portion of thespindle 27 passing through the cap 28 on the top of the standards 1 and`2 and has thereupon a hand-wheel 29 which is normally out of contactwith the said caps, as shown. From the foregoing descripti on it isobvious that the full weight of the weights 15 15, multiplied by theleverage, acts directly upon the upper roll 5, Vthe amount of pressurebeing governed by the position of the weights 15 15.

If it should be desired for any reason, such as placing cloth betweenthe rolls or for any IOO ' by the said gear 53.

other pur iose, the roll 5 can be raised from roll 7 an maintained outof contact therewith by means of the hand-'wheels 29, as said wheels maybe rotated to Contact the ca s 28', and by rotating still further thespindlis 27 will be raised, thereby raising the roll 5. The levers 21,rods 18, levers 16, and weights will of course be raised also. For thepurpose of mangling the cloth and forcing the sizing into the weave Iuse an engraved or roughened mangling-roll 30, which by means of thetrunnions 31 31 is rotatably mounted in adjustable boxes 32 32, whichare in turn slidably mounted upon ways 33 33 and adjusted toward or awayfrom the roll 7 by means of threaded spindles 34 34, which are screwedinto lugs 35 upon the standards 1 and 2, and carrying operating-wheels36 36. The periphery of the said roll 30 is roughened, as at 37, Fig. 3,and the projections may be of any configuration that does not have aknife-point or a point that would tend to perforate the cloth. Under theroll 7 I place a reservoir 38 for containing the heated sizing material39, Fig. 1, said reservoir being suitably secured to the standards, andunder therolls 7 and partially or entirely submerged in the sizing 39 Iplace a small roll 40, which is rotatably supported by the reservoir 3S.Said roll 40 is a mule or idler pulley to keep the cloth submerged inthe sizing as it passes along to the rolls 5 and 7. The cloth A is heldby brackets 41 and is passed over an idler 42, under the roll 40, upbetween the mangling-roll 30 and roll 7, then between the rolls 7 and 5at their pressure-points, and onto a receiving-winch 43. A more detaileddescription 'will hereinafter appear. As I desire to take advantage of ahigh belt speed transformed into a slower motion, I employ a system ofgearing and shafting comprising a driving-shaft 44, which carries afriction-pulley 45 and a pinion 46, the said pinion meshing with a gear47 upon a counter-shaft 48. The counter-shaft 48 carries a pinion 49,'which meshes with a gear 50 upon the eX- tended trunni on 9 of the roll7, which is rotated by said gear 50. A larger pinion 51 is also mountedupon the shaft 43 and meshes with an idler 52, adjustably mounted on thestandard 2, the said idler in turn meshing with a gear 53 upon theextended trunnion 31 of the mangling-roll 30, which is rotated Y Theproportion existing between the diameters of the pinion 49 and its gear50 and the larger pinion 51 and its gear 53 is such that the peripheralspeed of the roll 7 is somewhat slower than that of the mangling-roll30. The roll 30 therefore tends to lead in peripheral speed the roll 7,which has a grinding effect on the cloth, which acts to force the sizingthereinto. The train of gears is suitably mounted upon standards 54 54and an outlet 55 for the sizing is supplied.

The o eration of the machine is as follows:

Aldry ro l of cloth A is placed in the brackets 7the weave morethoroughly by the pressure of the weights 15 15. The cloth is thenrolled on the winch 43. When the roll A has 'become exhausted, the clothis then again passed through the machine and over the roll 5 andcollected. (See dotted and dash lines B, Fig. 2.) To get a smoothfinish, the roll 7 may be replaced by a compressed cotton roll. Ashereinbefore stated, one of the principal objects of this machine is toforce or grind the sizing into the weave of the fabric, which isaccomplished by the roughened periphery of the mangling-roll 30. Theproj ections upon the said periphery will tend to separate the weave ofthe fabric, at the same time forcing a large part of the sizingtherethrough, it being understood that the sizing is placed in thereservoir in a heated condition. The difference in peripheral speed ofthe material-roll 7 and mangling-roll 30 causes a slip at the point ofcontact of said roll, which has a grinding effect upon the cloth andsizing. The projections upon the surface of the m angling-roll will not,of course, perforate the fabric, the difference of speed being onlysuflicient to cause a moderate slip and not enough to tear the material.The pressure of the roll 30 upon the material-roll 7 can be varied, ashas been stated. The proportions of the gearing will be such as to givea slight difference in the speed of rolls 7 and 30, and any desireddifference in speed may be obtained by changing the gears 51 and 52.
